This invention relates to an improved radiator structure particularly 'for internal combustion engines, but also useful for space heating or cooling purposes. It is an object of this invention to provide an improved form of sectional radiator structure that allows more flexibility to meet the weaving and vibration encountered in'automotive service. The sectional structure also allows replacement of a damaged section without disturbing the air fins of other sections and eliminates head sheets and soldered joints. The sectional structure provides a much longer path for water travel thus secur- TF ing greater cooling capacity,. and thedistance of travel can bevaried tosuit the requirements of the installation by the addition or removal of sections as desired. It is also an object of this invention to provide an improved sectional radiator structure wherein each section is made up of interchangeable end boXes connected by thin walled flattened tubing having fins assembled thereon with spacingflanges integral with the fins.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanyingdrawings.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings: I

Figure 1 is a front elevation of a radiator 9 embodying the features of this invention.

Figure 2 is an enlarged vertical section on the line II-II of Figure 1.

Figure 3 is a plan View of one unit.

Figure 4 is a sectional view on the line IV-IV of Figure 3.

Figure 5 is a sectional view on the line V-V of Figure 4.

As shown on the drawings: I The automotive type of radiator chosen for illustration comprises a bottom tank 10 having a removable clean out plate 11 on the bottom, and mounting brackets 12,.on either end, the cold water outlet 13 being indicated in dotted lines on Figure 1. A top tank 14 has a filler opening 15 and a water inlet 16 Bid e s l es-a was r st m-f-rom the'top tank flowingintothetub'e se 'i'titms"tlirough an opening 1? on the-left hand sta or-estates; I v

Each tube 24 has a series of fins 29 pressed thereover to increase the radiating surface,; these'fins having flanges 30 struck from the hole in both directions parallel to the tubes, the flanges on either side of the fin alternating to meet similar flanges on the next fin to assure uniform spacing thereof while maintaining the erectness of each fin. The fins on adjacent tubes are staggered by omitting one fin from alternate tubes to improve the air circulation therethrough.

In the operation of this radiator the hot water from the engine enters the upper tank 14 through the inlet 15 and thence enters the box 18 of the first section through the opening 17 on the left side. The flow is then to the right in the first section and through the aligned boxes on the right hand side to the second section where the flow is towards the left, the entire volume of flow then going back and forth through the successive sections until it reaches the bottom tank 10 from which an I it is delivered to the engine again through the outlet 13.

It will thus be seen that the radiator of this invention is simple and easy to repair and is of high efliciency as a cooling or heating radiator due to the long path of water flow subjected to the action of the air.

Ne are aware that many changes may be made, and numerous details of construction may be varied through a Wide range without departing from the principles of this inven= tic-n, and we therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

We claim as our invention:

A sectional automobile radiator comprising top and bottom tanks, a plurality of interchangeable sections arranged therebetween, every one of said sections comprising a tube having flattened ends each entered and expanded in a solid block apertured to receive one end of the tube, the block at one end having an unobstructed passage opening at its upper face communicating with said tube, the

look at the other end having an unobstructed passage opening at its lower face communicating with said tube, said sections being positioned adjacent each other with the passage in one block communicating with the passage in an adjoining block, whereby said sections are connectedin series and Water may circulate freely from section to section, and bolts passing through said blocks and at opposite ends thereof and engaging said tanks -for securing said parts together in assembled relation.

In testimony whereof, we have hereunto subscribed our names at Chicago, Cook county, Illinois.
